The 1840 Democratic National Convention was held in Baltimore. The Democrats nominated PresidentMartin Van Buren for reelection in 1840 in spite of his unpopularity. Vice PresidentRichard M. Johnson had so many enemies that he failed to gain renomination. The Democrats could not agree on any vice presidential nominee. As a result, Van Buren became the only presidential nominee (since 1800) to seek election without a running mate.[citation needed]James K. Polk was an unsuccessful candidate for the vice presidential nomination; he received one electoral vote for vice president (from Virginia) in the general election.[1] Johnson managed to receive 48 electoral votes in the same manner.[1]
